 | That doesn't tell much. Appears like the program is just writing one word to the file then attempting to read it back. The open() statement you have will erase everything that's already in the file. If you want to add more words every time you run the program then you … |

| | Re: File Reading You are seeing all that garbage on the screen because the program is printing more array values than what was read from the file. In your example, 30 * 30 is 900, not 10,000, so the loop should stop at 900. You need to save the counter from line 17 … |

| | >>char filename[27]="c:\B2B Data\files\file.txt"; your compiler should have issued a lot of error messages about that line. Never ever ignore errors or warnings (in your own code) Most of the time, like the above line, warnings are actually errors waiting to crash your program. |
